MACD

MACD

MACD is an acronym for Moving Average Convergence Divergence. This tool is used to identify moving averages that are indicating a new trend, whether it’s bullish or bearish. After all, our #1 priority in trading is being able to find a trend, because that is where the most money is made.

MACD

With an MACD chart, you will usually see three numbers that are used for its settings.

  • The first is the number of periods that is used to calculate the faster moving average.
  • The second is the number of periods that are used in the slower moving average.
  • And the third is the number of bars that is used to calculate the moving average of the difference between the faster and slower moving averages.

For example, if you were to see “12,26,9” as the MACD parameters (which is usually the default setting for most charting packages), this is how you would interpret it:

  • The 12 represents the previous 12 bars of the faster moving average.
  • The 26 represents the previous 26 bars of the slower moving average.
  • The 9 represents the previous 9 bars of the difference between the two moving averages. This is plotted by vertical lines called a histogram (The blue lines in the chart above).

There is a common misconception when it comes to the lines of the MACD. The two lines that are drawn are NOT moving averages of the price. Instead, they are the moving averages of the DIFFERENCE between two moving averages.

In our example above, the faster moving average is the moving average of the difference between the 12 and 26 period moving averages. The slower moving average plots the average of the previous MACD line. Once again, from our example above, this would be a 9 period moving average.

This means that we are taking the average of the last 9 periods of the faster MACD line, and plotting it as our “slower” moving average. What this does is it smoothes out the original line even more, which gives us a more accurate line.

The histogram simply plots the difference between the fast and slow moving average. If you look at our original chart, you can see that as the two moving averages separate, the histogram gets bigger. This is called divergence, because the faster moving average is “diverging” or moving away from the slower moving average.

As the moving averages get closer to each other, the histogram gets smaller. This is called convergence because the faster moving average is “converging” or getting closer to the slower moving average. And that, my friend, is how you get the name, Moving Average Convergence Divergence! Whew, we need to crack our knuckles after that one!

Bollinger Squeeze

The Bollinger squeeze is pretty self explanatory. When the bands “squeeze” together, it usually means that a breakout is going to occur. If the candles start to break out above the top band, then the move will usually continue to go up. If the candles start to break out below the lower band, then the move will usually continue to go down.

Bollinger Squeeze

Looking at the chart above, you can see the bands squeezing together. The price has just started to break out of the top band. Based on this information, where do you think the price will go?

Bollinge Squeeze

If you said up, you are correct! This is how a typical Bollinger Squeeze works. This strategy is designed for you to catch a move as early as possible. Setups like these don’t occur everyday, but you can probably spot them a few times a week if you are looking at a 15 minute chart.

So now you know what Bollinger Bands are, and you know how to use them. There are many other things you can do with Bollinger Bands, but these are the 2 most common strategies associated with them. So now you can put this in your trader’s toolbox, and we can move on to the next indicator.

Bollinger Bands

Bollinger Bands

Bollinger bands are used to measure a market’s volatility. Basically, this little tool tells us whether the market is quiet or whether the market is LOUD! When the market is quiet, the bands contract; and when the market is LOUD, the bands expand. Notice on the chart below that when the price was quiet, the bands were close together, but when the price moved up, the bands spread apart.

Bollinger Bands

That’s all there is to it. Yes, we could go on and bore you by going into the history of the Bollinger band, how it is calculated, the mathematical formulas behind it, and so on and so forth, but we really didn’t feel like typing it all out.

In all honesty, you don’t need to know any of that junk. We think it’s more important that we show you some ways you can apply the Bollinger bands to your trading.

The Bollinger Bounce

One thing you should know about Bollinger Bands is that price tends to return to the middle of the bands. That is the whole idea behind the Bollinger bounce (smart, huh?). If this is the case, then by looking at the chart below, can you tell us where the price might go next?

Bollinger Bounce

If you said down, then you are correct! As you can see, the price settled back down towards the middle area of the bands.

Bollinger Bounce

That’s all there is to it. What you just saw was a classic Bollinger bounce. The reason these bounces occur is because Bollinger Bands act like mini support and resistance levels. The longer the time frame you are in, the stronger these bands are. Many traders have developed systems that thrive on these bounces, and this strategy is best used when the market is ranging and there is no clear trend.

Exponential Moving Average

Exponential Moving Average

Exponential Moving Average (EMA)

Although the simple moving average is a great tool, there is one major flaw associated with it. Simple moving averages are very susceptible to spikes. Let me show you an example of what I mean:

Let’s say we plot a 5 period SMA on the daily chart of the EUR/USD and the closing prices for the last 5 days are as follows:

Day 1: 1.2345
Day 2: 1.2350
Day 3: 1.2360
Day 4: 1.2365
Day 5: 1.2370

The simple moving average would be calculated as
(1.2345+1.2350+1.2360+1.2365+1.2370)/5= 1.2358

Simple enough right?

Well what if Day 2’s price was 1.2300? The result of the simple moving average would be a lot lower and it would give you the notion that the price was actually going down, when in reality, Day 2 could have just been a one time event (maybe interest rates decreasing).

The point I’m trying to make is that sometimes the simple moving average might be too simple. If only there was a way that you could filter out these spikes so that you wouldn’t get the wrong idea. Hmmmm…I wonder….Wait a minute……Yep, there is a way!

It’s called the Exponential Moving Average!

Exponential moving averages (EMA) give more weight to the most recent periods. In our example above, the EMA would put more weight on Days 3-5, which means that the spike on Day 2 would be of lesser value and wouldn’t affect the moving average as much. What this does is it puts more emphasis on what traders are doing NOW.

Exponetial Moving Average

When trading, it is far more important to see what traders are doing now rather than what they did last week or last month.

Simple Moving Average

Simple Moving Average

Simple Moving Average (SMA)

A simple moving average is the simplest type of moving average (DUH!). Basically, a simple moving average is calculated by adding up the last “X” period’s closing prices and then dividing that number by X. Confused??? Allow me to clarify.

If you plotted a 5 period simple moving average on a 1 hour chart, you would add up the closing prices for the last 5 hours, and then divide that number by 5. Voila! You have your simple moving average.

If you were to plot a 5 period simple moving average on a 10 minute chart, you would add up the closing prices of the last 50 minutes and then divide that number by 5.

If you were to plot a 5 period simple moving average on a 30 minute chart, you would add up the closing prices of the last 150 minutes and then divide that number by 5.

If you were to plot the 5 period simple moving average on the a 4 hr. chart………………..OK OK, I think you get the picture! Let’s move on.

Most charting packages will do all the calculations for you. The reason we just bored you (yawn!) with how to calculate a simple moving average is because it is important that you understand how the moving averages are calculated. If you understand how each moving average is calculated, you can make your own decision as to which type is better for you.

Just like any indicator out there, moving averages operate with a delay. Because you are taking the averages of the price, you are really only seeing a “forecast” of the future price and not a concrete view of the future. Disclaimer: Moving averages will not turn you into Ms. Cleo the psychic!

Moving Averages

Here is an example of how moving averages smooth out the price action.

On the previous chart, you can see 3 different SMAs. As you can see, the longer the SMA period is, the more it lags behind the price. Notice how the 62 SMA is farther away from the current price than the 30 and 5 SMA. This is because with the 62 SMA, you are adding up the closing prices of the last 62 periods and dividing it by 62. The higher the number period you use, the slower it is to react to the price movement.

The SMA’s in this chart show you the overall sentiment of the market at this point in time. Instead of just looking at the current price of the market, the moving averages give us a broader view, and we can now make a general prediction of its future price.

Price

Price Smoothies

A moving average is simply a way to smooth out price action over time. By “moving average”, we mean that you are taking the average closing price of a currency for the last ‘X’ number of periods.

Moving Average

Like every indicator, a moving average indicator is used to help us forecast future prices. By looking at the slope of the moving average, you can make general predictions as to where the price will go.

As we said, moving averages smooth out price action. There are different types of moving averages, and each of them has their own level of “smoothness”. Generally, the smoother the moving average, the slower it is to react to the price movement. The choppier the moving average, the quicker it is to react to the price movement.

Fibonacci Extension

Fibonacci Extension

The next use of Fibonacci you will be applying is that of targets. Let’s start with an example in an uptrend.

In an uptrend, the general idea is to take profits on a long trade at a Fibonacci Price Extension Level. You determine the Fibonacci extension levels by using three mouse clicks. First, click on a significant Swing Low, then drag your cursor and click on the most recent Swing High. Finally, drag your cursor back down and click on the retracement Swing Low. This will display each of the Price Extension Levels showing both the ratio and corresponding price levels.

On this 1-hour USD/CHF chart, we plotted the Fibonacci extension levels by clicking on the Swing Low at 1.2447 on 08/14/05 and dragged the cursor to the Swing High at 1.2593 on 08/15/05 and then down to the retracement Swing Low of 1.2541 on 08/15/05. The following Fibonacci extension levels created are 1.2597 (0.382), 1.2631 (0.618), 1.2687 (1.000), 1.2743 (1.382), 1.2760 (1.500), and 1.2777 (1.618).

Fibonacci Extension

Now let’s look at what actually happened after the retracement Swing Low occurred.

  • The market rallied to the 0.500 level
  • fell back to the retracement Swing Low
  • then rallied back up to the 0.500 level
  • fell back slightly
  • rallied to the 0.618 level
  • fell back to the 0.382 level which acted as support
  • then rallied all the way to the 1.382 level
  • consolidated a bit
  • then rallied to the 1.500 level

Fibonacci Extension

You can see from these examples that the market often finds at least temporary resistance at the Fibonacci extension levels - not always, but often. As in the examples of the retracement levels, it should be apparent that there are a few problems to deal with here as well. First, there is no way of knowing which level will provide resistance. The 0.500 level was a good level to cover any long trades in the above example since the market retraced back to its original level, but if you didn’t get back in the trade, you would have left a lot of profits on the table.

Another problem is determining which Swing Low to start from in creating the Fibonacci Extension Levels. One way is from the last Swing Low as we did in the examples; another is from the lowest Swing Low of the past 30 bars. Again, the point is that there is no one right way to do it, and consequently it becomes a guessing game.

Alright, let’s see how Fibonacci extension levels can be used during a downtrend. In a downtrend, the general idea is to take profits on a short trade at a Fibonacci price extension level since the market often finds at least temporary support at these levels.

On this 1-hour EUR/USD chart, we plotted the Fibonacci extension levels by clicking on the Swing High at 1.21377 on 07/15/05 and dragged the cursor to the Swing Low at 1.2021 on 08/15/15 and then down to the retracement High of 1.2085. The following Fibonacci extension levels created are 1.2041 (0.382), 1.2027 (0.500), 1.2013 (0.618), 1.1969 (1.000), 1.1925 (1.382), 1.1911 (1.500), and 1.1897 (1.618).

Fibonacci Extension

Now let’s look at what actually happened after the retracement Swing Low occurred.

  • The market fell down almost to the 0.382 level which for right now is acting as a support level
  • The market then traded sideways between the retracement Swing High level and 0.382 level
  • Finally, the market broke through the 0.382 and rested on the 0.500 level
  • Then it broke the 0.500 level and fell all the way down to the 1.000 level

Fibonacci Extension

Alone, Fibonacci levels will not make you rich. However, Fibonacci levels are definitely useful as part of an effective trading method that includes other analysis and techniques. You see, the key to an effective trading system is to integrate a few indicators (not too many) that are applied in a way that is not obvious to most observers.

All successful traders know it’s how you use and integrate the indicators (including Fibonacci) that makes the difference. The lesson learned here is that Fibonacci Levels can be a useful tool, but never enter or exit a trade based on Fibonacci Levels alone.
